Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention uses the roof of a passenger car to erect advertising boards, display boards, etc. and rotates them. The present invention relates to an in-vehicle public information display device suitable for informing passersby, passing vehicles, etc. of information under special environments.

(Prior Art) Conventional in-vehicle display bodies have mainly been used to display information in the front and rear directions of a vehicle in which the display body is mounted.
In other words, this type of vehicle is often used for the purpose of informing passing vehicles of information such as traffic accidents and road construction, and for this reason, the display mounted on the vehicle is displayed at the front and rear along the road. It would be good if possible. Since most of the display content regarding the vehicle is, so to speak, a cautionary note for the following vehicle, the number of types of display content does not need to be very large.

Therefore, with this type of vehicle-mounted display board, it is necessary to consider the position of attached parts such as rotating lights and speakers attached to the display board that can be raised and lowered, or to raise and lower the display board by remote control or by using a vehicle. The purpose of the improvement was to make it possible to adjust the display speed according to the speed of the display, to lock the undulating state of the display board, and to protect the display board itself.

60-61789).

In response to this trend, a display device (1983-1993) was developed in which the direction of the display board, which can be freely raised and lowered, can be rotated at least 90 degrees in the horizontal direction.
(Refer to Publication No. 162388), and a rotating signboard device in which the display surface of the display board rotates in the horizontal direction has also been devised, which is a signboard device in which the display board does not rise or fall (see Utility Model No. 162388).
-Refer to Publication No. 26561).

(Problems to be Solved by the Invention) However, the rotation operation in the horizontal direction in the former display device is merely an auxiliary function of the display board provided in a manner that it can be raised and lowered.

Moreover, all of these conventional undulating display boards are limited to two modes of change: a lying state and an upright state, and cannot be used at any angle from a lying state to an upright state, and cannot be used at any time or place. , it is impossible to hope for more effective display depending on the situation.

On the other hand, the latter type of rotating signboard device displays a signboard attached to the surface of the frame around the frame by rotating it in the horizontal direction. Like the display board mentioned above, it cannot be folded into a lying position, and when transported,
There were some inconveniences during storage. Moreover, since the large-scale rotating signage device is loaded in a state where it is always upright, it lacks maneuverability and cannot be expected to be displayed quickly to the scene of an emergency such as a traffic accident.

Therefore, this invention was devised to solve the above-mentioned problems, and it improves the discriminative power of the display mounted on a vehicle, making it possible to always provide effective display in response to any situation at any time and place. The purpose of this invention is to provide an in-vehicle public information display device.
